Chainstay Protector on Yukon

I went the old stand by route when a chainstayguard came up and decided to wrap an old tube around it. However i came to the realization that the rear derailleur cable runs across it. In trying to wrap it up I noticed that the cable was just being smashed. Im worried that this would result in either horrible shifting, frame and guard destrustion or even both. Any advice on how to wrap it up but not cut down on shifting proficiancy?
